Predicting interface and spin states in armchair graphene nanoribbon junctions
We present a theoretical analysis of interface states emerging at junctions between armchair graphene nanoribbons of varying widths. By exploring diverse width combinations and junction geometries, we demonstrate that predicting the precise number of interface states requires considerations beyond the topological classification alone; specifically, the width differences and bonding configuration at the interface play crucial roles. For junctions involving ribbons with small gaps, we further exa…

Ex Situ Fabrication of Superconducting Nanostructures for Low-Temperature STM
Nanofabrication enables flexible experimental design but is often incompatible with scanning tunneling microscopy and spectroscopy (STM/STS) due to the latter's stringent surface quality requirements. Here, we present a fabrication strategy that combines ex situ nanolithography with in situ ultrahigh-vacuum (UHV) cleaving to produce atomically clean, nanopatterned superconductor/topological insulator (TI) heterostructures suitable for high-resolution STM/STS. In our initial Design I, nanoribbon…

Graphene Nanoribbons as a Majorana Platform
Graphene nanoribbons support a range of electronic phases that can be controlled via external stimuli. Zigzag-edged graphene nanoribbons (ZGNRs), in particular, exhibit an antiferromagnetic insulating ground state that transitions to a half-metallic phase under a transverse electric field or when embedded inside hexagonal Boron Nitride. Here, we consider a simple model of a heterostructure of a ZGNR with an Ising superconductor and show that, the Ising superconductor with a parent s-wave spin-s…

Comparative Study of Strain-Engineered Thermoelectric Performance of 2D-Xene Nanoribbons
The quest for efficient and scalable thermoelectric materials has catalyzed intense interest in quasi 1D nanoribbons, where reduced dimensionality and structural tunability can decouple key transport parameters to enhance energy conversion. In this work, we present a unified comparative study of the thermopower in armchair nanoribbons derived from five archetypal 2D materials: graphene, silicene, germanene, stanene and phosphorene. Using a tight binding model parametrized by first principles in…

Optimized Synthesis and Device Integration of Long 17-Atom-Wide Armchair Graphene Nanoribbons
Seventeen-carbon-atom-wide armchair graphene nanoribbons (17-AGNRs) are promising candidates for high-performance electronic devices due to their narrow electronic bandgap. Atomic precision in edge structure and width control is achieved through a bottom-up on-surface synthesis (OSS) approach from tailored molecular precursors in ultra-high vacuum (UHV). This synthetic protocol must be optimized to meet the structural requirements for device integration, with ribbon length being the most critic…

Tunable Interlayer Excitons in Bilayer Graphene Nanoribbons
Vertically stacked van der Waals structures are promising platforms that enable layer engineering, opening new avenues for the quantum control of elementary excitations, including optically generated bound electron-hole pairs. Here we employ excited-state density functional calculations to demonstrate strong interlayer excitonic coupling in one-dimensional van der Waals nanostructures derived from armchair graphene nanoribbons. The excitonic response exhibits prominent peaks in the near-infrare…
